[Saki Rinku] Kyou Kara Zenra Toukou 3

Uniformed schoolgirls and an adult man move from a cramped train carriage and a shared meal into a classroom chemistry lab, where posed photographs, pet-like compliance, exposed bodies, and awkward confessions steadily turn the outing into an exhibitionist fantasy. One student fights to retain her composure while another responds with embarrassment and reluctant curiosity, giving the group encounters a teasing, shifting rhythm. Black-and-white linework, Japanese sound effects, laboratory glassware, train seats, and snapshot-like framing lend the sprawling school-themed story a candid, nervous energy.
